Apparently two brands make them, Cremodul and Trustnice; maybe a few others, but I’m not keen on using knock-offs because my teeth are quite fragile and apparently both of those brand knock-offs are much harder on the teeth. It also appears you can only really get them online from Amazon, which I’m definitely not keen on - out of the two, I’d rather throw extra money at Oral-B than a single £1 at Amazon.
